Geothermal

Did you know you can use the Earth to heat or cool your home? Our geothermal solutions use a buried loop system to produce energy right in your back yard.

Invest in Geothermal HVAC Systems for Your Home

Your backyard has the potential to be the energy source for your heating and cooling comfort. While outdoor air temperatures fluctuate throughout the year, ground temperatures four to six feet below the Earth’s surface remain relatively moderate and constant all year. This is because the Earth absorbs 47% of its heat energy from the sun.

Geothermal HVAC systems circulate a water-based solution through a buried loop system in the ground to take advantage of these constant temperatures, which means a single piece of equipment has the ability to heat and cool your home, as well as provide some or all of your hot water.

When geothermal technology is used to heat your home:

Cold water circulates through the earth loop

Water absorbs energy from the earth in the form of heat

Energy is carried via the water to the heat exchanger in the heat pump

Refrigerant in the heat exchanger absorbs energy from the water

Water leaves the heat exchanger and circulates through the earth loop to pick up more energy

Refrigerant gas that contains the energy travels to the compressor.

In the compressor, the refrigerant temperature rises to 160°

Superheated refrigerant then travels to the air heat exchanger

The heat pump’s blower circulates air across the air coil, increasing the temperature of the air

This air is then blown through ductwork to heat your home

After refrigerant releases its heat energy to the air, it then flows to the earth loop and starts the cycle again

When geothermal technology is used to cool your home

Warm water circulates through the earth loop

Water releases energy into the earth in the form of heat

The water, now cooler, flows to the heat exchanger in the heat pump

In the heat exchanger, hot refrigerant gas from the compressor releases its heat into the water

Water increases in temperature and releases the energy to the ground

Refrigerant gas releases its heat energy, becomes a cold liquid, and travels to the heat exchanger

The heat pump blower circulates warm, humid air across the cold air coil

Air is then blown through ductwork to cool your home

Refrigerant in air coil picks up heat energy from the air and travels to the compressor

When refrigerant leaves the compressor, it flows to the earth loop and starts the cycle again
